Prosperity Horse free games begin with three Gong scatters

The trade write-up of the launch, whose stated source is the studio's own announcement, puts the trigger at three or more scatter symbols. A review of the title identifies that symbol as a Gong and adds that it counts anywhere in view from three positions up to seven — which is what a seven-reel grid allows and what makes a seven-scatter hit possible at all rather than theoretical. A catalogue describing the game's own purchase window lists the same ladder from three to seven.

That catalogue is also the only source we hold for the counts. It lists ten, fifteen, thirty-five, forty-five and sixty free games against three, four, five, six and seven scatters respectively. It is a single page for that detail, so it is written here as what the catalogue lists rather than as what the game does, and the step from fifteen to thirty-five is steep enough that a reader meeting a different ladder elsewhere should not assume this one is wrong. Our own source names the round and never counts it, which is why the attribution has to be explicit.

This is the part worth reading twice. In most games with a progressive multiplier the bonus round starts the multiplier again at one, and the base game's accumulation is simply the price of admission. Here it is not. The trade coverage states that the multiplier built up during the base game remains active during the feature, so the round begins wherever the session had got to. Combined with a multiplier that does not reset between spins in the base game either, the two halves of the game are one continuous accumulation.

The studio's head of corporate communications, quoted in that same write-up, describes the intent in those terms: a combination of expanding symbols and multipliers giving a sense of development through a session, at a volatility level aimed at players who want it. That is a fair description of what the mechanics do, and it is also, read carefully, an admission about the shape of the outcomes. A game whose value accumulates across a session is a game where most individual spins contribute rather than pay, and where the interesting results sit at the end of a sequence.

The trade write-up adds that an earlier title from the same studio used the same non-resetting structure, carrying its own named multiplier into free spins instead of restarting it. That makes this a house pattern rather than a claim about one game, which is a small point in favour of the description being accurate.

Inside the round, expanding symbols occur more frequently than they do in the base game. On a five-reel grid that would be a modest adjustment. On seven reels and five rows it is not: a symbol that fills its reel covers five of thirty-five positions, and with the line count already able to sit well above its base twenty-eight, an expanded position is being evaluated against far more lines than it would be in the ordinary state. Expansion and the dynamic line system work in the same direction.

Our source describes the presentation rather than the frequency: the round keeps the same seven-by-five field, the same symbol hierarchy and the same counters, so nothing has to be relearned when the feature starts, and a locked horse Wild is still a locked horse Wild. A distinct feature frame and a games counter mark the round without shrinking the grid to a decorative panel. That continuity of layout is the visible counterpart to the continuity of the multiplier.

The studio lists a buy feature for this title, and a catalogue describes the window it opens: confirming the purchase places three, four, five, six or seven scatters directly and awards the corresponding count of games. The trade coverage is careful about the availability, and so is this page: it says the option is provided for players in certain markets. That phrasing in this industry means availability follows the rules where the account is held, and it is not a sentence to paraphrase into something more definite.

What can be said plainly is that a paid entry is not a way of improving anything. It buys the round at a price set by the game's model, and the model is the configured build the operator installed — one of five, somewhere between 86 and 98 per cent. A purchase does not change which build is running and does not change what it returns. The same goes for the Super Bet switch a catalogue describes on the interface: a quarter more stake for a better chance of reaching the round is a different way of spending, not a better one.

Both controls are described here because they sit on the screen and a reader will meet them. Neither is advice. There is no bet size, no number of spins and no order of operations that makes a high-volatility slot behave differently, and any page offering one is selling something.

Beside Free Games, our source lists ReSpin support and multiplier support among the game's features, and a catalogue's feature table adds retriggering to the list. Neither of them explains what the respin does or what retriggers under which condition, and this page is not going to invent an explanation. The honest statement is that both facilities are listed for the title and that the mechanics behind them are not published anywhere we hold.

The same source lists Jackpot Race, UP Tournaments and WinReplay. Those are not features of the game at all — they are platform options an operator can switch on around it, and the trade write-up describes the jackpot race in exactly those terms, as a timed competitive element an operator can use. They are mentioned here only so a reader who meets them in a feature list knows which side of the line they fall on. On the reels there are four things: lines growing, Wilds locking, Gates multiplying and envelopes resolving.
